1988 ford bronco 2

I have a 1988 ford bronco 2,2.9L V6 one day while running down the road it died from lack of fuel I changed the fuel filter 1st then the internal fuel pump in the gas tank under the vehicle I see it has a external pump on the frame plus it has some kind of canister before it goes to the fuel filter I cannot get it to run there is no gas going to the front of the engine compartment what would be the best way to lick this problem does the external pump when the key is turned on and is it possible that the canister is plugged up need some help here
Thank you
